Removing of the Watery theme is an enhancement in sense of "cleanup". The code was not maintained and partly broken. To have this theme in the image was a problem for management of the two default
Pharo themes because the Watery theme was
superclass of them and added a significant level of complexity and mess.
But let's be positive. I can imagine that this thread has a huge flame potential so I spent a few minutes to prepare Watery Theme as a standalone package (see the attached *.st file). And no, it was not a simple file-out operation. So I hope that people that want to use the Watery Theme will rather discuss in what repository to place it and who will maintain it. In Pharo we want to focus on two basic themes - one white and one dark. We simply see no reason why this theme should not be an optional external package.
